Dear all list-members I have just recently registered to this mailing list. I am in the beggining of my PhD which general scope is the hydraulic and environmental performance evaluation of urban drainage systems. I would be very grateful if you could send me references, contacts, web sites and other suggestions related to this subject.. Looking forward to hearing from you Yours sincerely Maria Adriana Cardoso Research Assistant of the Sanitary Engineering Division of LNEC (National Civil Engineering Laboratory of Portugal) %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
